Answer:
y = x + 3
Step-by-step explanation:
Slope-intercept form is represented by the formula . We can write an equation in point-slope form first, then convert it to that form.
1) First, find the slope of the line. Use the slope formula and substitute the x and y values of the given points into it. Then, simplify to find the slope, or
:
Thus, the slope of the line must be 1.
2) Now, since we know a point the line intersects and its slope, use the point-slope formula and substitute values for
,
, and
. From there, we can convert the equation into slope-intercept form.
Since represents the slope, substitute 1 in its place. Since
and
represent the x and y values of a point the line intersects, choose any one of the given points (either one is fine) and substitute its x and y values into the equation, too. (I chose (0,3).) Finally, isolate y to find the answer:
